OIL-BURNER.

- Application filed March 6l, 1915. Serial N o. 12,650.

a citizen of theUnited States, residing atV y East Cleveland, inthe county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Oil-Burners, of which the following is a full, clear, and exact description,reference being had to the accompanying .drawings.

This invention'frelates to oil stoves and more particularly to stoves of the .type wherein perforated ommingling tubes are employed for the purpose ofproducing a' blue flame, in a manner well known in the art.- It is the, enteral-purpose of this invention to provid?J a burner of this character wherein the top of the wick and the surrounding wick tubes will be kept cool and .wherein this result may be secured even should' either or both of the commingling tubes become unseated to s uchan extent as to admit air beneath the bottom or bottoms thereof. vThis necessarily results in maintaining the combustion more uniform and efficient and-in prolonging the life of the wick. A further and'more specific object of the in vention is to provide an improved seating arrangement for the commingling tubes; also an improved construction of wick tubes.

Further and more generally stated, the inf ventio'nl may be deiined as consisting of the combinations of elements set forth in the claims appended hereto and illustrated in the drawings forming part hereof, wherein Fig- .ure 1 represents a vertical sectional view taken through a burner constructed in accordance with my invention; Fig. 2 a cross sectional view corresponding to the line 22 of Fig. 1, the parts at the right hand side of the burner being broken away; and Fig. 3 a sectional detail of armodiied construction of the upper ends of the wick tubes and of the parts coperating therewith.

Referring to the drawings forming part of this specification, 1 denotes an inner and 2 an outer wick tube formin therebetween an annular space to which oimay be supplied through the pipe '3 and a lateral supply connection 4 secured to the outer wick tube and provided with arbore communicating with an* opening 5 `1n said wick tube. The burner is secured to the pipe 3 by means of Vthe-hook 6 which'is secured to and' depends from theI inner `tube and by means of the connection 4, the manner of securing the burner to the tube being substantially the same as that disclosed in J eavons Patent No. 951,612 issued March 8th, 1910. The width of the space between the tubes 1 and 2fwith the exception of the upper portions of said tubes-is considerably greater than the thickness of the wick '7 which is interposed between said tubes, thus providing a well for the reception of oil and a space within which the wick and itscarrier 8 may freely rise'and fall. At a suitable distance below their tops, the .wick tubes are bent-the inner tube downwardly and inwardly as shown at 9 and the outer tube downwardly and outwardly as shown at 10, the metal of the tubes being doubled orbent upon itself thereby to form downwardly inclined inner and outer seats for commingling tubes, to be described hereinafter. Above these seats, the inner tube is. bent outwardly, as shown at 11, and the outer tube inwardly, as shown at 12, whereby the upper portions of such tubes are in substantial engagement with and form a contacting guide for the upper end of the wick, as indicated at 13 and 14. The ex- -a cap 19 which may have a central perfqration 20. The cap 19 may be conveniently fitted within the top of the inner commingling tube by means of a downwardly projecting flange 21 which fits snugly within thel top of said com'mingling tube and is shownas seated within the lugs 22, which may be struck from the metal constituting said comQ mingling tube.

23 denotes the. outer commingli'ng tube,

this tube, when seated, preferably extending above the inner commingling tube. A drum 24 having a large opening 25 in the top thereof surrounds the commingling tubes and is 'provided with an annular bottom 26 which projects inwardly toward the outer wick tube, thence downwardly as shown at27 below the seat 10, and thence inwardly below said seat, as indicated at- 28, forming an annular air receiving space 29 with the outer wick tube below said seat. The bottom plate 26 is provided with perforations 26a for admitting air to the space surrounding the outer commingling tube. Within the inner wick tube there is located an air distributer 30, said distributer being of the shape of an inverted bowl having a central opening 31 in the to thereof and having its. inverted wall or siiirt extending substantially paral` lel with the inner wick tube to which it may be secured by means of the channel members 32said members being with their flanges bearing respectively against the inner wick tube and the wall of the distributer and being secured thereto in any convenient manner, as by soldering or brazing. VThe upper end of this'distributer is substantially Hush with the bottom of the inner commingling tube when the latter is resting upon its seat.

The comminglin tubes and the drum are shown as connected by means of cross rods 33, 34 whereby they may be handled as a unitary structure. without disturbing their proper relation toene another and to the wick tube seats.

With the parts arranged as described, it is believed that the general operation willbe apparent. Air-:which is necessary to produce the combustion of the vgases or vapors beu tween the tubes 17 and A23 is supplied to the outertube through the annular opening or slot 29 and beneath'the seat l0. Impinging upon said seat'it is and -outwardly and thence upwardly to the outer surface of the commingling tube 23, the perforations whereof it enters and Qper ates in the usual manner toward the production of a blue flame. Additional air for the outer tube 23 is admitted through the open! ings 26".

The air wick tube Hows 1n greater part in a substan- 30 and the inner wall of said :inner wick tube, impinging upon and beneath the seat 9 and being deflected downwardly and 1nwardly thereby and thence passing upwardly into the interior of the inner conuningling tube. Some aira limited quantity-passes through the opening 3l, and the major portion of the air within the` inner comminglingtube passes into the space bct-weensaid tube and the outer tube and operates in the usual manner toward the production ot' a blue flame.

It will be seen that the top portions of the inner and outer wick tubes and the seats for the commingling tubes particularly are vsubjected to upwardl.y moving currents of air tending to keep these parts cool. y v Attention has been invited hereinbefore to preferably arranged which ascends within the inner 15 the inwardly and outwardly projecting beads to be discharged in a narrow rapidly moving revents the maintenance of a e tops of the burner tubes. The narrowness of the slits provided between the tops of the inner and outer wick tubes and their respective commingling tubes prevents anything but the finest particles of charred wick or other material from. passing therethrough. Furthermore, should any material be discharged upon the seats, especially` at the time when the commingling tubes are removed,las for ing the wick, the downward inclination of the seats will preventl practically all such material from adhering to or remaining on the seats. In Fig.

sheet which ame below t figures of the drawings mainly in the fact that'the Wick tubes are not made :from the same sheet of metal as the lower portions and the seats which are formed at the junction of the upper and lower portions of these tubes are not downwardly inclined. The upper portion 33 of th from a sheet of metal having a bead 34 at its top substantially identical with the bead aving an outwardly projecting flange 35 at upper end of the tubel is crimped, as shown at 36, thereby forming a seat for the co1nmingling tube 17'.l In like manner the per end 37 of the outer wick tube 2 is formed from a comparatively narrow sheet ot'metal 'havine an outwardl )ro'ectino bead 38 at its upper end similar to the bead 16 and .having at iis bottom an outwardly projecting v i flanO'e 3f) about which the u )er end of the b 1 n tube 2 1s crimped, as

formed by uniting the top of the tube 2 and the bottom ot' the tube section 37, the' outer comming-ling tube 23 ls supported.

Thel construction described herein is simple and economical ot production but is particularly efficient for the purposes of realizing the objects of' the invention. Burners of the type shown herein, while applicable for other e inner wick tube is formedits lower end about which theshown at 40. Onthescat tops of the wick Y purposes, have been found to be advantageous for heating places such as garages and tents, as well as for general heating purposes.
